How effective is ICSI for male factor infertility?

In ICSI, an embryologist selects a sperm and injects it directly into an egg. This bypasses the need for sperm to reach and enter the egg on its own, so it may be considered when sperm numbers, movement, or shape are a concern, or when previous fertilisation was unsuccessful.

ICSI does not repair the underlying reason for reduced sperm production and it does not remove factors related to egg quality, embryo growth, the womb lining, or implantation. The clinic will interpret fertilisation and embryo development together with both partners’ assessment.

Ask why ICSI is recommended rather than conventional IVF, how sperm will be collected, and whether a urology review or genetic assessment is appropriate. Share medicines, illnesses, previous operations, and any difficulty providing a sample. Follow the clinic’s medication and appointment instructions, then ask how fertilisation and embryo updates will be reported.

During fertility treatment, contact the clinic about severe pelvic pain, heavy bleeding, fever, marked abdominal swelling, vomiting, or shortness of breath. After an embryo transfer, urgent advice is needed for severe pain, heavy bleeding, faintness, or breathing difficulty.

What male factor is ICSI intended to address? Is fresh or surgically retrieved sperm being considered? How will embryo quality and the womb be assessed? What happens if fertilisation or development is lower than expected?
